ABSTRACT:
An image processing apparatus for applying video effects to input image signals. The apparatus comprises a first signal processor consisting of first and second multipliers for multiplying first and second input image signals by coefficients K and 1-K (where 0.ltoreq.K.ltoreq.1) respectively, and a first adder for adding the output signals of the first and second multipliers to each other; a second signal processor consisting of third and fourth multipliers for multiplying the output signal of the first adder and a third input image signal by coefficients K' and 1-K' (where 0.ltoreq.K'.ltoreq.1) respectively, and a second adder for adding the output signals of the third and fourth multipliers to each other; a memory having a plurality of areas to store first and second key frame data; a controller for controlling the first and second signal processors on the basis of the first and second key frame data stored in the memory; and an input circuit for inputting the first and second frame data to the memory.
